【考案の詳細な説明】 こノ考案は、オートバイ等に用いる小型エンジンのエア
クリーナの吸気騒音低減装置に関する。
[Detailed Description of the Invention] This invention relates to an intake noise reduction device for an air cleaner of a small engine used in a motorcycle or the like.

クリーナを装着する必要があって、場所の制約を大きく
受け、騒音を少くすることがむつかしい。
It is necessary to attach a cleaner, which greatly limits the space and makes it difficult to reduce noise.

この考案はかかる点に鑑み、小さいエアクリーナで有効

Figure 3 shows an embodiment of the present invention;
In addition to what is shown in the figure, a second guide pipe 11 is communicated in the middle of the interference pipe 6, and the second guide pipe 11 is opened near the intake pipe inlet 9 section.

作用について説明する。The effect will be explained.

騒音を消音する。
The cleaner body 1 serves as an expansion chamber and mainly muffles noise in the high frequency range.

Intake air is taken in from both the short intake pipe 5 and the long interference pipe 60.

干渉管6は発生する低周波域の騒音に合せて長さを設定

The length of the interference tube 6 is set according to the noise in the low frequency range that is generated, and when there are multiple peaks, the second guide tube 11 is provided, so that the noise in the predetermined low frequency range can be reduced by interference.

しかも短い吸気管5も開口しているので吸気抵抗も大き
くならず、互に干渉させることができる。
Moreover, since the short intake pipe 5 is also open, the intake resistance does not become large and they can interfere with each other.

As explained above, this invention has a short intake pipe protruding from one side of the cleaner body, a spiral interference pipe around the intake pipe, and a double-layered structure with the inner end of the interference pipe wrapped around the intake pipe. Since the outer end of the interference pipe is communicated with the guide pipe that opens at the intake pipe inlet of the cleaner body, the sound at the intake pipe inlet is transmitted through the intake pipe with a short passage, the guide pipe and the guide pipe. It is divided into a long passage consisting of an interference tube, and when it is opened to the atmosphere, it meets with the O, effectively attenuating the forces and intake noise that interfere with each other.

しかも上記干渉管は渦巻状に形成されでいることにより
比較的場所を要することなく十分長い管路が構成され、
波長の長い低周波域の騒音を十分減衰させることができ
、吸気騒音の低減が図れる。
Moreover, since the interference tube is formed in a spiral shape, a sufficiently long pipe can be constructed without requiring a relatively large space.
Noise in a low frequency range with a long wavelength can be sufficiently attenuated, and intake noise can be reduced.

しかも上述のように短かい吸気管も併設しであるので吸
気抵抗も少くできる。
Furthermore, as mentioned above, since a short intake pipe is also provided, intake resistance can be reduced.
